HashCode.writeBytesTo介绍

[英]Copies bytes from this hash code into dest.
[中]将此哈希代码中的字节复制到dest。

代码示例

@Override
HashCode makeHash(Hasher[] hashers) {
 byte[] bytes = new byte[bits() / 8];
 int i = 0;
 for (Hasher hasher : hashers) {
  HashCode newHash = hasher.hash();
  i += newHash.writeBytesTo(bytes, i, newHash.bits() / 8);
 }
 return HashCode.fromBytesNoCopy(bytes);
}
